ok i have the ms4 since the summer its a bad *** cam, now im looking for a head that goes with it i was thinking of PRC LS6 Stage 2.5 CNC Ported Heads or the PRC LS6 stage 1 i cant decide which direction to go, i saw that one article with the ls6 heads and the ms4 which was tight but i keep hearing that LS6 stage one has low torque so what do you guys think and any other opition on other heads that i can go with besides the 2 that i pick thanks

Write directly to texsas speed and ask them which heads best match with the ms4 question will be best answered by them.

The Stg.1 LS6 heads will clear fine. The Stg. 2.5 LS6 heads will require flycutting to clear the stock pistons. Both setups work well and produce great numbers time and time again!

I'm installing the prc ls6 stage 2.5's now with the ms4 and a fast 90/90 set up. I got them milled to 59cc's and i'm going to flycut. should be a good set up.

Just look and see what heads continue to flow and don't back up before the max lift of the cam.
